SURGICAL TREATMENT OF PATELLAR INSTABILITY IN ADOLESCENT DANCERS

Background: Adolescent dancers may be a high-risk population for patellofemoral instability (PFI), but the condition remains under-investigated, to date, in this sub-group of athletes. Purpose: The purpose of this study was to (1) investigate the descriptive epidemiology of PFI in adolescent dancers, (2) analyze the efficacy of various patellar stabilization procedures within this population, and (3) compare PFI in dancers to a larger control group of matched, non-dancer athletes. Methods: A retrospective review of athletes, ages 10 to 19, who presented to a single tertiary care center with PFI between 2008 and 2017 was performed. Based on each patient’s primary sport, the cohort was divided into a dancer and a non-dancer control group. Demographics, clinical and radiologic features, surgical stabilization technique, and postoperative course and clinical outcomes were collected. Independent categorical groups were tested using chi squared and Fisher exact tests. Results: 258 adolescent athletes were included, 41 of whom were dancers, all females. This group was therefore matched with a control group of similarly aged, all-female athletes with PFI (Table 1). 54 athletes had bilateral PFI, yielding 285 knees for analysis. There was no difference between dancer and non-dancer athletes’ age, BMI, laterality, mechanism of injury, nor number of preoperative instability events. However, dancers had lower Dejour Classifications (p=0.044), smaller patella inclination angles (20.9±8.14 versus 25.0±9.84; p=0.004), and smaller Caton-Deschamps Indices (1.18±0.161 versus 1.25±0.189; p=0.041). Among dancers, there was no association between surgical stabilization technique and rates of recurrent instability (p=0.418) nor re-stabilization procedures (p=1.0) (Table 2). However, dancers who underwent tibial tubercle osteotomy (TTO) had higher rates of subsequent, non-stabilization procedures (66.7%), all for implant removal, compared to those undergoing isolated medial retinacular repairs (MRP) (3.8%) (p<0.001). There was no difference between the dancer and non-dancer athletes’ rates of recurrent instability (p=0.297), re-stabilization procedures (p=0.061), nor subsequent non-stabilization procedures (p=0.242). Conclusions: Female dancers with PFI have similar demographic and clinical features as other female athletes with PFI, but have lower rates or less severe trochlear dysplasia, lateral tilt and patella alta. Therefore, the ligamentous laxity inherent in dancers may be a more powerful risk factor for PFI than other non-modifiable risk factors. Notably, the TTO was a powerful stabilization procedure for this sub-population with low rates of recurrent instability episodes and no revision stabilization procedures performed. Rates of implant removal surgery following TTO may be substantial, though this may be technique or surgeon dependent. Tables/Figures: [Table: see text][Table: see text]

AbstractThe tibial tubercle–trochlear groove (TT–TG) distance was originally described for computed tomography (CT) but has recently been used on magnetic resonance imaging (MRI) without sufficient evidence demonstrating its validity on MRI. The current review aims to evaluate (1) whether there is a difference in the TT–TG distances measured using CT and MRI, (2) whether both the TT–TG distances measured using CT and MRI could be used to differentiate between patients with or without patellofemoral instability, and (3) whether the same threshold of 15 to 20 mm can be applied for both TT–TG distances measured using CT and MRI. The review was conducted using the preferred reporting items for systematic reviews and meta-analyses (PRSIMA) guidelines. All studies that compared TT–TG distances either (1) between CT and MRI or (2) between patients with and without patellofemoral instability were included. A total of 23 publications were included in the review. These included a total of 3,040 patients. All publications reported the TT–TG distance to be greater in patients with patellofemoral instability as compared to those without patellofemoral instability. This difference was noted for both TT–TG distances measured on CT and on MRI. All publications also reported the TT–TG distance measured on CT to be greater than that measured on MRI (mean difference [MD] = 1.79 mm; 95% confidence interval [CI]: 0.91–2.68). Pooling of the studies revealed that the mean TT–TG distance for the control group was 12.85 mm (95% CI: 11.71–14.01) while the mean TT–TG distance for patients with patellofemoral instability was 18.33 mm (95% CI: 17.04–19.62) when measured on CT. When measured on MRI, the mean TT–TG distance for the control group was 9.83 mm (95% CI: 9.11–10.54), while the mean TT–TG distance for patients with patellofemoral instability was 15.33 mm (95% CI: 14.24–16.42). Both the TTTG distances measured on CT and MRI could be used to differentiate between patients with and without patellofemoral instability. Patients with patellofemoral instability had significantly greater TT–TG distances than those without. However, the TT–TG distances measured on CT were significantly greater than that measured on MRI. Different cut-off values should, therefore, be used for TT–TG distances measured on CT and on MRI in the determination of normal versus abnormal values. Pooling of all the patients included in the review then suggest for 15.5 ± 1.5 mm to be used as the cut off for TT–TG distance measured on CT, and for 12.5 ± 2 mm to be used as the cut-off for TT–TG distance measured on MRI. The Level of evidence for this study is IV.

Tibial Tubercle Osteotomy

Background: Historically, the most commonly utilized technique to address recurrent patellofemoral instability (PFI) was a combined proximal and distal realignment, specifically the tibial tubercle osteotomy (TTO) with a proximal medial retinacular plication/reefing/tightening/repair (MRP). Rising interest in the medial patellofemoral ligament reconstruction (MPFLR) over the last decade, now frequently performed as a more powerful isolated proximal realignment procedure, has prompted debate over the optimal technique to treat this common condition. Hypothesis/Purpose: The study hypothesis was that no difference would be detected in recurrent PFI rates or revision surgery rates between patients who underwent TTO-MRP vs. MPFLR. Methods: With cohorts derived from a large, single-center PFI database of 523 patients who underwent a variety of stabilization procedures, 114 eligible MPFLR patients were matched to 109 TTO patients based on age, gender, BMI, and TT-TG distance. Propensity score matching was conducted using logistic regression models to produce 1:1 matching, and a caliper of 0.2 standard deviations of the estimated propensity score was used to for the nearest neighbor matching algorithm. Final matching procedure resulted in 84 MPFLR patients and 84 TTO patients. These were compared on demographics and post-operative clinical results. Results: Demographic and radiologic comparisons of the cohorts are shown in Table 1, with the only difference between groups being an expected higher rate of patients with open physes in the MPFLR cohort. Table 2 shows the TTO-MRP group had longer follow up times, but comparable rates of return to sports. The MPFLR group had a higher rate of recurrent instability, but not to a significant degree, and a significantly higher incidence of revision patellar stabilization surgery (p<0.001). The TTO group had a higher rate of additional knee surgery, the majority of which were implant removal for TTO screws. Conclusion: The TTO-MRP shows equivalent or superior results to the MPFLR for treatment of PFI. However, implant removal may be common with TTO, though this may be somewhat technique-dependent. In the current landscape of increasing interest and utilization of MPFLR as an all-encompassing PFI surgery, the influence of distal bony realignment to minimize recurrence should not be underappreciated.

Objectives: Medial epicondyle apophyseal avulsion fractures sustained during throwing represent an understudied, severe variant of medial epicondyle apophysitis, or ‘Little League elbow’. The current study sought to characterize presenting features, treatment options, and clinical results of a large cohort of pre-adolescent and adolescent patients who presented with these fractures. Methods: Skeletally immature athletes with medial epicondyle apophyseal avulsion fractures sustained during throwing from 2003-2017 at a tertiary-care pediatric referral center were identified. Exclusion criteria were fractures sustained during non-throwing activity or prior elbow fracture. Medical records and radiographic images were reviewed for study variables. Treatment decisions were made independently by fellowship-trained pediatric orthopaedic surgeons or sports medicine physicians on a case-by-case basis. Patients treated with open reduction and internal fixation (ORIF) were compared to those treated non-operatively, and all fracture patients were compared to a larger control group of patients diagnosed with medial epicondyle apophysitis/Little League elbow with no fracture. Results: During the study period, a total of 317 patients were diagnosed with Little League elbow due to medial epicondyle apophyseal overuse injury, 50 of whom (16%) sustained a discreet, radiographically confirmed epicondyle fracture sustained during a single throw. Median age of the fracture cohort at presentation was 13.1 years (range 8 years – 16 years). Forty-nine fracture patients (98%) were male baseball pitchers and one (2%) was a male football quarterback. Fracture patients had significantly higher median BMI (21.3 kg/m2 vs. 19.2kg/m2, p=0.004) than the apophysitis control group, but there was no significant difference in age. Of the 37 patients with documentation regarding pre-injury symptoms, 31 patients (84%) described pre-existing medical elbow pain prior to their acute injury, while 6 (16%) denied pain prior to the inciting throw. Of the 12 patients (24%) with documented shoulder exams at presentation, 5 (42%) demonstrated glenohumeral internal rotation deficit (GIRD). Twenty-three patients (46%) were treated with ORIF (22 single screw fixation; 1 suture anchor fixation), while 27 (54%) were treated non-operatively. Median fracture displacement was significantly greater in operative patients than non-operative patients (5.0mm vs. 3.0mm, p=<.001), with all ‘minimally displaced’ (<4mm) fractures undergoing non-operative treatment (Figure 1). Multivariable analysis determined that for each additional mm of displacement, the odds of surgical intervention increased by 6.4 times (OR=6.36; 95% CI=1.83-22.07; p=.004), when controlling for age and BMI. All patients returned to their throwing sport (RTS) at a median of 12.8 weeks post-diagnosis, but 13 (26%) developed recurrent elbow pain, with no significant difference in in RTS time or recurrence rate between treatment cohorts. Nine of twenty-two (41%) screw ORIF patients underwent secondary implant removal, with no significant difference in this rate between those with or without a washer. Conclusions: Medial epicondyle apophyseal avulsion fractures in youth throwers represent a severe variant of Little League elbow, constituting approximately 16% of cases within the condition’s spectrum. These fractures may be effectively treated with either non-operative measures, particularly minimally displaced fractures <4mm, or ORIF, though >40% of operative patients may require implant removal. A large majority of patients reported medial elbow pain prior to fracture, suggesting this severe presentation of Little League elbow may be preventable.

Introduction: Older patients are a high-risk population in the Emergency Department (ED) for poor outcomes after ED visit, including return presentation and hospital admission. Little is known however about outcomes in older patients identified as “low acuity” by triage. We aim to describe the characteristics, ED workup, disposition, and 14-day outcomes of ED patients 65 years and up who are triaged as low acuity and compare them to a younger cohort. Methods: This health records review was done in a Canadian tertiary care ED. Included patients received a Canadian Triage Acuity score (CTAS) of 4 or 5 and were either 65 years and up (“older” group), or 40-55 years (controls). Data collected included patient demographics, tests and services involved in ED, and disposition. Return ED visit and hospital admission rates at 14 days were tracked. Data were analyzed descriptively and chi-square testing conducted to assess for differences (p < 0.05) between groups. A pre-planned stratified analysis of patients 65-74 years, 75-84, and 85 and older was conducted. Results: 350 patients (mean age 76.5, 56.6% female) were included in the older group and 150 in the control group (mean age 47.3, 55.3% female). Most patients presented with musculoskeletal or skin complaints (older cohort: 28.6% extremity pain/injury, 10% rash, 8.9% laceration, versus control 30% extremity pain/injury, 14.7% rash, 14.0% laceration) and were triaged to the ambulatory care area (88.6% elderly, 99.3% control). Older patients were significantly more likely than younger controls to be admitted on index visit (5.0% vs 0.3% admit rate, p=0.016). They had a trend towards increased re-presentation rates within 14 days (13.7% vs 8.7% control, p=0.11) and were more likely to be admitted on re-presentation (4.0% vs 0.7%, p=0.045). In sub-group analysis, very elderly patients (85 years and up, n=79) were more likely to be admitted (8.9%, p=0.003). Conclusion: Patients 65 years of age and older who present to the ED with issues labelled as “less acute” at triage are 16 times more likely to be admitted than younger controls. Patients 85 years and up are the primary drivers of this higher admit rate. This study characterizes “low acuity” elders presenting to ED and indicates these patients are high risk for re-presentation and admission within 14 days.

Currently, Russian skaters are delivering incredible performances worldwide. In this regard, diverse social groups show increasing interest in this sport. Thus, professionals pay much attention to the coaching for win-win outcomes. It is especially important for single female skaters at the competitions where few hundredths of a point determine results of several participants from Russia, and at the same time dozens of points separate them and skaters from other countries on the podium. The aim of the research is to test the techniques of teaching multi-rotation jumps to female skaters aged 10-11. These techniques are part of training methodology, and they consider harmony, interconnection and versatility of sport training in general. These techniques include special exercises with the use of “Rotator” simulator. Materials and methods of the research. In our research, we used the review and analysis of scientific and methodological literature, pedagogical observations, pedagogical testing; pedagogical experiment, mathematical and statistical processing of the results. The experiment covered two groups of female athletes born in 2007-2008, with 8 people in each group. All the participants came from the «Zvezda» Center of Physical Culture and Sports of the North-Western administrative district of Moscow. Research results and discussion. Participants of the experimental group were performing the developed sets of exercises on general physical training, special physical training (including “Rotator” vestibular simulator) and training on skating rink during six months. The research revealed a significant increase in the technical and physical fitness of the participants of this subgroup. Conclusion. The developed set of “Rotator” simulator exercises, as well as complexes of auxiliary and special training exercises with increasing coordination complexity are effective in teaching multi-rotation jumps to female skaters aged 10-11 compared with the standard exercises performed in the control group.

Background While the majority of bleeding complications after a percutaneous kidney biopsy (PKB) occur early (≤24 h), delayed onset bleeding complications (>24 h) have been rarely reported and can be catastrophic for the patient. Purpose To describe the incidence, risk factors, and outcomes of delayed bleeding complications after PKB. Material and Methods We retrospectively studied native and graft kidney biopsies in patients who developed delayed bleeding complications (>24 h) after the biopsy performed in the Department of Nephrology and Renal Transplantation of a tertiary care medical institution in north India between January 2014 to December 2018. Results Of the 4912 renal biopsies reviewed, 20 patients (16 men, 4 women; 0.40%) had a delayed biopsy bleeding complication. Of these patients, 95% had major bleeding complications requiring blood transfusions and 85% needed intervention like gelfoam/coil embolization. Despite intervention, one patient (5%) had mortality due to complications of bleeding and sepsis. When compared to a control group of patients with early biopsy bleed, patients with the delayed biopsy bleed had similar demographic and clinical profiles except for higher pre-biopsy hemoglobin and lower systolic and diastolic blood pressure. Conclusion A post-PKB delayed onset bleed is not uncommon, and the vast majority of these patients had major bleeding complications requiring blood transfusions and/or intervention like embolization. They had a similar demographic and clinical profile presentation as early bleed patients. Meticulous outpatient monitoring and patient education after discharge may be useful to detect this complication promptly and to intervene early to have good patient outcome.

Objective Reporting patient symptoms due to nasal septal perforation (NSP) has been hindered by the lack of a validated disease-specific symptom score. The purpose of this study was to develop and validate an instrument for assessing patient-reported symptoms related to NSP. Study Design Validation study. Setting A tertiary care center. Methods The Nasal Obstruction Symptom Evaluation (NOSE) scale was used as an initial construct to which 7 nonobstruction questions were added to measure septal perforation symptoms. The proposed NOSE-Perf instrument was distributed to consecutive patients evaluated for NSP, those with nasal obstruction without NSP, and a control group without rhinologic complaints. Questionnaires were redistributed to the subgroup with NSP prior to treatment of the perforation. Results The study instrument was completed by 31 patients with NSP, 17 with only nasal obstruction, and 22 without rhinologic complaint. Internal consistency was high throughout the entire instrument (Cronbach α = 0.935; 95% CI, 0.905-0.954). Test-retest reliability was demonstrated by very strong correlation between questionnaires completed by the same patient at least 1 week apart ( r = 0.898, P < .001). Discriminant validity was confirmed via a receiver operating characteristic ( P < .001, area under the curve = 0.700). The NOSE-Perf scale was able to distinguish among all 3 study groups ( P < .001) and between NSP and nasal obstruction ( P = .024). When used alone, the NOSE scale could not discriminate between NSP and nasal obstruction ( P = .545). Conclusions The NOSE-Perf scale is a validated and reliable clinical assessment tool that can be applied to adult patients with NSP.

The aim of this research was to compare the effects of a technique-specific high-intensity interval training (HIIT) protocol vs. traditional taekwondo training on physical fitness and body composition in taekwondo athletes, as well as to analyse the inter-individual response. Utilising a parallel controlled design, sixteen male and female athletes (five females and 11 males) were randomly divided into an experimental group (EG) that participated in the technique-specific HIIT and a control group (CG) that participated in traditional taekwondo training. Both groups trained three days/week for four weeks. Squat jump (SJ), countermovement jump (CMJ), 5-metre sprint (5M), 20-metre shuttle run (20MSR), taekwondo specific agility test (TSAT), multiple frequency speed of kick test (FSKTMULT), total kicks, and kick decrement index (KDI), as well as body composition were evaluated. Results indicate that there are no significant differences (p > 0.05) in the factors group and time factor and group by time interaction (p > 0.05). Although percentage and effect size increases were documented for post-intervention fitness components in TSAT, total kicks, KDI, and 20MSR, responders and non-responders were also documented. In conclusion, a HIIT protocol based on taekwondo-specific technical movements does not report significant differences in fitness and body composition compared to traditional taekwondo training, nor inter-individual differences between athletes.

The Mean

Background: Tibial tubercle–trochlear groove (TT-TG) distance is often used as a measure of lateralization of the TT and is important for surgical planning. Purpose: To investigate if increased TT-TG distance measured on axial magnetic resonance images is due to lateralization of the TT or medialization of the TG. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 84 knees (28 normal [NK], 28 with trochlear dysplasia [TD], and 28 with patellar dislocation without TD [PD]) were examined. The medial border of the posterior cruciate ligament (PCL) was chosen as the central anatomic landmark. The distance from the TT to PCL (TT-PCL) was measured to examine the lateralization of the TT. The distance from the TG to the PCL (TG-PCL) was measured to examine the medialization of the TG. Between-group differences were investigated by use of 1-way analysis of variance. Results: The mean values for TT-TG distance were 8.7 ± 3.6 mm for NK, 12.1 ± 6.0 mm for PD, and 16.7 ± 4.3 mm in the TD group ( P < .01). The mean values for TT-PCL distance were 18.5 ± 3.6 mm for NK, 18.5 ± 4.5 mm for PD, and 21.2 ± 4.2 mm in the TD group ( P = .03). The mean values for TG-PCL distance were 9.6 ± 3.0 mm for NK, 7.1 ± 3.4 mm for PD, and 5.1 ± 3.3 mm in the dysplastic group ( P < .01). Conclusion: The present results indicate that increased TT-TG distance is due to medialization of the TG and not lateralization of the TT. Knees with TD had increased TT-TG distance compared with the knees of the control group and the knees with PD. The TT-PCL distance did not differ significantly between groups, whereas the TG-PCL distance declined with increased TT-TG.

Abstract Background There is limited published data in Lebanon evaluating the impact of supplemental education for anticoagulants use, especially DOACs, on clinical outcomes such as bleeding. The study aims to assess the impact of pharmacist-conducted anticoagulation education and follow-up on bleeding and readmission rates. Methods This study was a randomized, non-blinded interventional study conducted between August 2017 and July 2019 in a tertiary care teaching Lebanese hospital. Participants were inpatients ≥18 years discharged on an oral anticoagulant for treatment. Block randomization was used. The control group received the standard nursing counseling while the intervention group additionally received pharmacy counseling. Phone call follow-ups were done on day 3 and 30 post-discharge. Primary outcomes included readmission rates and any bleeding event at day 3 and 30 post-discharge. Secondary outcomes included documented elements of education in the medical records and reported mortality upon day 30 post-discharge. Results Two hundred patients were recruited in the study (100 patients in each study arm) with a mean age of 73.9 years. In the pharmacist-counseled group, more patients contacted their physician within 3 days (14% versus 4%; p = 0.010), received explicit elements of education (p < 0.001) and documentation in the chart was better (p < 0.05). In the standard of care group, patients were more aware of their next physician appointment date (52% versus 31%, p < 0.001). No difference in bleeding rates at day 3 and 30 post-discharge was observed between the groups. Conclusions Although pharmacist-conducted anticoagulation education did not appear to reduce bleeding or readmission rates at day 30, pharmacist education significantly increased patient communication with their providers in the early days post-discharge. Trial registration Lebanon Clinical Trial Registry LBCTR2020033424. Retrospectively registered. Date of registration: 06/03/2020.
